Leaving the ISP's MX as an backup.

Why don't you use a service such as easyDNS to host your DNS records? They automatically store your mail for up-to five days if your server is down and forward it to you when your server is back on-line. It's not free but relatively inexpensive and, IMO, worth the money.

Just to thrown my own personal preference into the pot have a look at DynDNS :: Mailhop Backup MX relatively low cost and I have never experienced any issues with them.

This thread seems to be quiet what I am looking for. I have setup a split domain making my zimbra server as the primary MX and my freebsd server as the secondary MX. I have added users in my freebsd to my zimbra. The domain of my freebsd is my.account.com and I created the same domain in my zimbra (my.account.com) users@my.account.com has been added to zimbra as users@my.account.com. I followed the following wiki as suggested. I did setup a relay of my.account.com on my zimbra server to forward all incoming internet mails to users that have not yet been migrated to zimbra.
The users that are being migrated to zimbra can receive emails from the internet, but the ones that still resides in freebsd cannot receive emails from the internet. Instead, the emails are being rejected and the senders receive a bounce email:
This is the mail system at host cmsout02.mbox.net.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

: host zimbra.my.account.com[xxx.xx.xxx] said: 550
5.1.1 : Recipient address rejected: my.account.com
(in reply to RCPT TO command)

I am not sure what I am doing wrong. Also, do I need to configure or make any changes in the freebsd server just so the server is aware that it act as a secondary or slave server?

thanks
